So i am 4 and a half weeks into flower and 4 out of 5 are doing really nice but the biggest one is getting leaves curling under but not taco like, the stems are starting to get a purple tinge. The other 4 are perfect they are all the same strain fem cheese from ghs. Any idea's? The first 2 photos are of the one with the def the rest are the other 4.
It's not Mg. I don't know what it is though. This is a good resource page for nutrient issues. https://www.icmag.com/ic/showthread.php?t=11688
Thanks guys i wil flush them tonight then back off the nutes a little and see how that goes, it doesnt seem to be bothering her too much but i dont want it to get worse.
Thanks guys i will give them a double water flush then drop my ec down to about 1.4 for a week or so then slowly raise it
